Sorry, I don't think there is a way to fix them unless you have a food dehydrator or maybe can put them in a room with a dehumidifier. Now that they've drawn up so much moisture from the air, I don't think they will taste fresh though even if you can dry them out. Sorry this happened! It has happened to me too. Cookies just totally fell apart, crumbled in my fingers when I tried to pick them up.
